FLOAT FOR CONTROLLING SHUT-OFF VALVES.

SPECIFICATION formingpart of Letters Patent No. 687,625, dated No ember26, 1901.

Serial No. 70,035. (No model.)

To all whom it may concern:

Be it known that I, WINFIELD E. HINSDALE, a citizen of the UnitedStates, residing at New York, in the borough of Manhattan, county andState of New York, have made a new and useful Invention in Floats forControlling Shut-Off Valves, of which the following is a specification.

My invention is directed to a novel form of float for use in connectionwith shut-01f valves-such, for instance, as are found in cisternwatecclosets and railway and other water-tanks-in short, in any placewhere it is desired to have the flow of water controlled by the actionof a float when it (the water) reaches a certain level. I

My invention will be fully understood by referring to the accompanyingdrawings, in which- Figure 1 is a side elevational view of my improvedfloat. Fig. 2 is a side elevational View as seen looking at Fig. 1 fromthe bottom toward the top of the drawings, the means for attaching thevalve-controlling rod to the gripping or supporting band about the floatbeing shown in sectional view, a part of the float being broken away andalso shown in sectional view for the purpose of more effectuallyillustrating the invention. Fig. 3 is an end elevational view as seenlooking at Fig. 1 from right to left, the body of the float proper beingshown in dotted lines.

Shut-0E valves have heretofore been controlled by means of floats madeof thin sheet metal, such as copper, in the form of two hemisphericalcups, said cups being soldered together and attached to avalve-controlling rod. This type of float, however, is faulty in i thatthe acids and other materials usually fact the imperfect deposition ofthe electroplating material often leaves points of attack for the acidsin the water, so that they are open to the same objection as are thetwopart cups first described. A still further novel form of float hasbeen constructed, consistin g of a hollow glass ball having a moldedneck threaded exteriorly, to which threaded neck a coupling andvalve-controlling rod are attached. In the construction of this float,however, the neck and the hall are made separate and afterward fusedtogether. A brass coupling screw-threaded interiorly is then secured tothe threaded neck and the valvecontrolling rod in turn secured to thecoupling. In fusing the glass parts together the best joint is notalways effected, and it is found in practice that the neck and the balloften become'separated, thus making it worthless. My improved form offloat is designed to overcome all of these objections and will be fullyunderstood by referring now to the accompanying drawings in detail, inwhich- A is a hollow glass ball so constructed when blown as to have twoheads B B located on opposite sides ofits equator, thereby leaving agroove or channel G for receiving a drawband D, provided with holes oropenings at its opposite ends adapted to receive screws F F, extendinginto lugs or extensions E E of a coupling-piece G. This coupling-pieceis in turn screw-threaded, as shown, so as to receive one end of thevalve-controlling rod R, having screw-threads at its opposite ends andadapted to be secured to the valve-rod or other attachment ordinarilyused in connection with such devices in the usual way.

In putting this float together the ends of the draw-band D are bentoutward, as shown in Fig. 2, and it is laid in the groove C between thebeads B B, one end thereof being secured by one of the screws F directlyto the coupling-piece G, after which the' other end is drawn intoposition and the second screw F secured in place,there being sufiicientdraw or tension upon the band D and couplingpiece G when the screws arefirmly set to cause said band to firmly grip and secure thecoupling-piece against the ball, after which the valve-controlling rodis secured in place and the completed article is ready for transportation and use.

' I am aware that it is old in the art to support a glass-ball float bya series of curved rods or arms of metal secured to a valve-controllingrod or lever by a set-screw, as disequator; together with a surroundinggrip-- closed in United States patent to G. B. Moore, No. 588,461,granted August 17,1897, and that it is also old to support metallic-ballfloats made in two parts, such as. hereinbefore referred to, by astudded disk and straps or bands which surround and secure the ball tothe disk, as disclosed in United States patent to V. D. Anderson, No.640,073, granted December 26, 1899, and I make no claim hereinafterbroad enough to include such structures.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

1. As an article of manufacture a hollow glass float provided with agroove around its ping-band provided with holes at its opposite ends, acoup1ing-piece and screws for securing the opposite ends of said band tothe V coupling-piece, substantially as described.

2. As an article of manufacture a hollow glass float provided with agroovearound its equator, a surrounding band provided with holes at itsopposite ends; a coupling-piece, screws for securing the opposite endsof said band to the coupling-piece and a. valve-controlling rod securedto the coupling-piece, substantially as described.

3. As an article of manufacture a hollow glass float A having a grooveor channel 0 in the plane of its equator; a surrounding grip ping-band Dprovided with holes at its opposite ends; together with a coupling-pieceG, screws F, F adapted to secure the opposite ends of said band to thecoupling-piece and a valve-controllin g rod B provided with screwthreadsat its opposite ends for securing one end to the float and the other tothe valve to be controlled, substantially as described.

4. As an article of manufacture a'glass float A having a groove orchannel Gin the plane of its equator; a surrounding gripping-band Dprovided with holes at its opposite ends; a coupling-piece G having anextension or neck screw-threaded internally; screws F, F adapted tosecure the opposite ends of the gripping-band directly tothecoupling-piece; together with a valve-controlling rod screwthreaded atits opposite ends in such manner that one end thereof may be secureddirectly to the neck of the coupling-piece and the other to the valve tobe controlled, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
